Broken Kode Discussion Forums

I've been having some trouble trying to customize lists on the sidebar.  For example, I'd like to have one list on the sidebar that *doesn't* use the bullet.jpg image as a bullet while all the other lists on the sidebar continue to use the image as a bullet.

I figured this could easily be done in CSS by adding the following to the corresponding list in sidebar.php:

  <li><h2><?php _e('My List'); ?></h2>
  <div id="mylist">
  <ul>
   <li>Item 1</li>
   <li>Item 2</li>
   </ul>
   </div>
  </li>

and, then, adding the following to style.css:

#mylist ul li {
   background-image: none;
   list-image: none;
}

However, none of the properties that I change in mylist in the CSS file seem to have any effect on the list items displayed in the sidebar (I've tried "#mylist ul li ul li" as well and it still doesn't work).  Any thoughts how I can change the formatting for only one of the lists on the sidebar?

Thanks!
